Matthew 19:9

Except it be for fornication - See on Matthew 5:32 ; (note). The decision of our Lord must be very unpleasant to these men: the reason why they wished to put away their wives was, that they might take others whom they liked better; but our Lord here declares that they could not be remarried while the divorced person was alive, and that those who did marry, during the life of the divorced, were adulterers; and heavy judgments were, denounced, in their law, against such: and as the question was not settled by the schools of Shammai and Hillel, so as to ground national practice on it therefore they were obliged to abide by the positive declaration of the law, as it was popularly understood, till these eminent schools had proved the word had another meaning. The grand subject of dispute between the two schools, mentioned above, was the word in Deuteronomy 24:1 , When a man hath taken a wife - and she find no grace in his sight, because of some Uncleanness, ערות eruath : - this the school of Shammai held to mean whoredom or adultery; but the school of Hillel maintained that it signified any corporeal defect, which rendered the person deformed, or any bad temper which made the husband's life uncomfortable. Any of the latter a good man might bear with; but it appears that Moses permitted the offended husband to put away the wife on these accounts, merely to save her from cruel usage.

In this discourse, our Lord shows that marriage, (except in one case), is indissoluble, and should be so: -
